I did this over on my forums, but we don't have enough people there to play along, so I'll give it a shot here. This is a hypothetical question. I know some die-hards might start throwing beer cans at their monitors yelling "how the fuck can you compare them?!". Just think if you had to choose one or the other. Afterwards make your own lists! I'm gonna mix up the genres, but generally try to keep the bands that are being matched in the same category, and era.

Abigail V.S. Barbatos = /. Dont like both much.
Tank V.S. Motorhead = /. Love both much!
Celtic Frost V.S. Venom = / but tough call, I tend to Venom
Warhammer V.S. Apokalyptic Raids = Warhammer but Apoklayptic Raids are excellent as well
Vulcano V.S. Holocausto = Vulcano , Holocausto had their Campo which was pretty great, after that they stunk and had this recent album which was okay. Vulcano have their immortal Bloody Vengeance MLP and the Live LP in disco which cant be really beaten for me in terms of classic southamerican metal, besides they still kill today
Impaled Nazerene V.S. Carpathian Forest = ImpNaz. I like some of CF's old stuff but Impaled Nazarene were so much better...
D.R.I. V.S. Cryptic Slaughter = DRI. Cryptic Slaughter are very cool though
Aura Noir V.S. Darkthrone = cant decide. UAFM is a favourite of mine, Black Thrash Attack also.
SSS V.S. Cross Examination = / (dont know either)
Beherit V.S. Archgoat = Beherit. I only really like the early MLP from Archgoat
Spearhead V.S. Revenge = Dont know Spearhead
Bestial Mockery V.S. Nifelheim = Nifelheim. Bestial Mockery were pretty good on the demos and the first LP, but Nifelheim have their untouchable first two albums.
